celine has $997 in an account. the interest rate is 9% compounded annually. to the nearest cent, how much interest will she earn in 2 years? use the formula $b = p(1 + r)^t$, where $b$ is the balance (final amount), $p$ is the principal (starting amount), $r$ is the interest rate expressed as a decimal, and $t$ is the time in years.
Answer
Answer:
184.43
Explanation:
Step1: Convert interest rate to decimal
$r = 9%=0.09$
Step2: Identify principal and time
$p = 997$, $t = 2$
Step3: Calculate the final amount
$B=p(1 + r)^t=997\times(1 + 0.09)^2=997\times1.09^2=997\times1.1881 = 1181.5357$
Step4: Calculate the interest
$I=B - p=1181.5357-997 = 184.5357\approx184.54$ (rounded to the nearest cent)
